Brady is rather isolated and most time forgotten kid. He has glasses and Schroder-like, blonde hair. He wears a blue shirt, dark blue pants, and white shoes.
Brady is rather shy when around people like in "The Forgotten" and when trying to express his feelings to Mavis. Also, his personality is very similar to Charlie Brown from Peanuts.
Brady is a pastiche of Charlie Brown from the famous comics named Peanuts. This is heavily revealed in the episode "The Forgotten" where he usually states his point of views within his mind and has a similar role as Charlie Brown as well as surprisingly sounded somewhat like him and has a crush on girl with red hair (similar to Charlie Brown's crush on the Little Red Haired Girl). He also a few times quotes Charlie Brown's main catchphrase "Good Grief". He also shows some traits from other characters from Peanuts, having almost Schroeder's hairstyle and being drawn with Marcie's glasses.
